供給するようにした吸気装置が知られている。The present invention relates to an air intake device that utilizes the inside of a main pipe constituting the body frame of a vehicle such as a motorcycle or three-wheeled vehicle as an intake passage (prior art). As shown in FIG. 6, a main pipe (2) extends rearward from the head pipe (1), and the main pipe (2), head pipe (1) and down pipe (3)
A gusset (0) is welded to the front end of the frame where the gas is concentrated, and an intake port (
5) is formed at the front of the main pipe (2), and an outside air inlet (8) is formed on the side of the gusset (0), and an air guiding member (7) is formed to open this outside air inlet (8) forward. ),
On the other hand, connect the rear part of the main pipe (2) to the air cleaner (8).
The air cleaner (
8) and from this air cleaner (8) via a connecting tube (8), an air intake device is known in which outside air is supplied to a carburetor (10).

のメインパイプの前部廻りに限定される。In other words, when using a water-cooled engine, a radiator must be installed, and the location where the radiator is installed must be a certain distance from the road surface, especially for off-road type motorcycles and tricycles. It is necessary to place the radiator in a high position. In addition, when considering the weight balance of the entire vehicle, it is preferable to place the radiator as close to the center of gravity as possible. Therefore, if a radiator is provided, its placement is limited to the area in front of the main pipe in front of the fuel tank.
